Tachometer problem:

Orginal tachometer has a dutycycle of 33/256 and dont like signals other than that.

I run the old open source-code (r027) and I made a successful change in it to make it work. but I will upgrade to newest firmware soon..

- Is it possible to add a new constant which define the duty of the tach signal in the newest firmware?

Yes, it is possible.
